Cambridge Environmental Research Consultants (CERC) uses DK v10 for Air Pollution and 3-D Visualization

January 24, 2014

U.K. based environmental engineering company CERC (www.cerc.co.uk) started using the TatukGIS Developer Kernel (DK) ActiveX edition in 2007 to develop the GIS mapping module for its ADMS air pollution modeling software. ADMS is used by hundreds of people in over 30 countries for dispersion modeling of urban air pollution and calculation of air pollution concentrations. Users include regulatory authorities, government organizations, industrial bodies, environmental consultancies and academic institutions.

The mapping module developed from the TatukGIS DK, called ADMS Mapper, is used to visualize and edit input data for the ADMS modeling software. Before ADMS Mapper became available, users of ADMS had to buy third party GIS software such as ESRI ArcGIS or MapInfo to visualize their modeling scenarios.

In 2013 CERC updated its Mapper application to use the TatukGIS DK v10 in order to take full advantage of the new 3-D mapping capabilities the DK component provides. The new Mapper v2 is now an ActiveX library (DLL) that is installed as a shared component so that it can be used by multiple products CERC develops. Accordingly, the Mapper v2 was released during October-December 2013 with the latest versions of ADMS-Urban, ADMS-Roads and ADMS-Airport. The flexibility of developing a plug-in GIS tool in-house using the TatukGIS SDK has meant CERC can provide stunning GIS capability in many products quickly and with reduced development costs.

ADMS is used to model the impact of existing and proposed industrial installations with respect to air quality standards such as the EU Air Quality Directive, UK Air Quality Strategy, US National Ambient Air Quality Standards (NAAQS), Chinese Class I, II and III, and WHO guidelines. Typical uses include IPPC authorizations, stack height determination, odor modeling, environmental impact assessments, and safety and emergency planning. Government customers of ADMS within the United Kingdom include the UK Health and Safety Executive (HSE), Environment Agency in England, Natural Resources Wales, Scottish Environmental Protection Agency (SEPA), Department of the Environment in Northern Ireland, and Food Standards Agency in the U.K.

ADMS Mapper allows the user to view, check, and edit their input
source details. Each road source is scaled to its width in the model.

Model attributes for each source can be viewed, and the sources can be displayed according
to their attributes. Here, roads have been colored according to their total traffic.

The Mapper can render pollutant concentrations output from the ADMS model.
